Saving Throw Will negates; Spell Resistance no


This awful ritual calls the Daemon Sultan of the Outer Gods from his throne at the center of existence to the caster’s location. Azathoth is allowed a Will saving throw to negate this ritual (his bonus is +31).

No tome is known to contain this spell, but servitors of the Outer Gods are eager to teach it or force others to perform it, as they require mortals to break the required Elder Signs.

When the ritual is successful, Azathoth manifests at influence stage 1 accompanied by 1d3 servitors of the Outer Gods and 1d10-1 other unspeakable creatures of great power from his court. Unless Azathoth is banished quickly, the completion of this ritual generally leads to the utter destruction of the planet to which he is summoned.
